How can organism's be so unique if the nucleotides making up DNA are all the same between organism's?​
Masja [62]

Every organism is unique, even though the nucleotides making up DNA are all the same, because the structure is different in every organism. In other words, it's just the order in which nucleotides are placed that differs each organism from one another.

What 3 functions do proteins have in a plasma membrane?*
Aliun [14]

Answer:

Explanation:

Proteins in the plasma membrane have several functions based on their components, location etc. For instance, if the protein transcends the entire plasma membrane it could be a transport protein, responsible for the import and export of certain molecules between the cell and the extracellular matrix (ECM). If the proteins are resting at the surface of the cell, facing the ECM, their role could be to detect components in the ECM, relaying a series of messages back to the nucleus so that the cell can ‘decide’ what it should do with this information (is it being told it should undergo apoptosis, should it begin to divide, should it migrate?). As well as this, it could be involved in the detection of foreign bodies such as pathogens. This is an extremely job for these proteins because if the cell does come in contact with a pathogen, the cell can use these proteins to engulf the pathogen and through a series of steps, present the antigen on their major histocompatibility complexes (either 1 or 2 depending on the cell type) or HLA’s for human cells. Thus it can be concluded that protein functions vary widely in the plasma membrane and due to the vast number of proteins that can be found there, it’s difficult to narrow down the exact main of functions of all these proteins put together.

Carolus Linnaeus developed a two-part naming system to refer to all living organisms. The two-part name, known as binomial nomen
Tju [1.3M]

The correct binomial nomenclature for humans is H. sapiens, in which H. is genus and sapiens is species.

<h3>What is binomial nomenclature?</h3>

The binomial nomenclature is a two-term naming system in which the name of every species is named specifically.

This naming system was developed by Carolus Linnaeus.

It is written as a genus with the following species.

For example the scientific name of the dog is Canis (genus) familiaris (species).

Thus, the scientific name of humans is H. sapiens.
